Seaside Engineering & Surveying (SEAS) has extensive experience performing hydrographic surveys and is recognized nationally as a leader in Hydrographic Surveying. SEAS personnel have completed numerous hydrographic surveys both multibeam and singlebeam on inland and coastal waterways. SEAS has completed projects for Mobile, Pittsburgh, Louisville, Jacksonville, Chicago, Nashville, Vicksburg, St. Louis, Rock Island, Little Rock and St. Paul US Army Corps of Engineers (USACE) Districts. SEAS has surveyed over 10,000 bank to bank singlebeam cross sections in the past five years on inland waterways.
SEAS currently fields three (3) Hydrographic Survey crews with multi-beam, single-beam and sidescan sonar data collection and data processing experience. These crews are capable of producing Finished Digital Products in the field, including Cross Sections, DTMs, CADD Contour Drawings and Dredge Volume Computations. SEAS hydrographic survey crew personnel are also experienced in Static and Kinematic GPS Control Surveys and processing using Leica GeoOffice and NGS OPUS. This experience enables SEAS to provide a quality product quickly, efficiently and economically. Using DGPS SEAS hydrographic survey crews provide real-time sub-meter horizontal survey accuracies. SEAS also broadcasts RTK corrections from local control at or near the project site. With SEAS’ Applanix PosMV we can perform highly accurate RTK or PPK surveys.
SEAS owns three custom built Scully’s survey workboats. Two are 22’ aluminum workboats with 7’ cabins (doors fore & aft) with trailers, with a dual frequency singlebeam transducer mounted in the centerline of the hull. The third boat is a 26 foot aluminum workboat with an 8 foot cabin (doors fore and aft). The rear deck is self bailing with a moon well for the deployment of singlebeam, multibeam, or side scan transducers. SEAS equipment includes «RESON 8124 and 7125 Multibeam systems « RESON 620 and 515 dual frequency fathometers « EdgeTech 4125 Side Scan « RESON SVP-14 and Odom Digibar Pro sound velocity profilers.
